I have filed application in Austriafion the 12th August, 1925, and in Germany on 7th May, 1926.

This invention relates to an apparatus for producing "or promoting artificlal breathing.

or respiration, which essentially consists of a bell-shaped, arched or curved member provided with a packing passing right round the rim of the said member, the latter being secured to the patient in such a manner, that between the breast and bellyof the patient and the said curved member is formed an air-tight space, in which the pressure of the air can be reduced andraised.

The essential feature of the present invention consists in that a pressure air-vessel and a suction air-vessel are interposed in the pipes which lead from the device producing the pressu'reand suction-reflect to the interior of the curved member, the said vessels being provided with adjusting valves and devices for measuring the pressure, which ,are independent of one another, in

'order to adjust according to requirement and separately the intensity of the employed pressure and suction. y

One mode of carrying out the present mvention is illustrated by way ,of'example on the accompanying sheet of drawings in which-- Fig. 1 shows the device in elevation, and Figs. 2'. and 3 two constructions of the curved member in sectional elevation.

In Fig. l, the. reference character 1 des-- ignates an electrically operated diaphragm air pump, which by means of wires 2, 2 can be connected totne plug 3 of the lighting mains. l designates a suction air-vessel, 5 a pressure air-vessel, and 6 and 7 are pipes, which establish communication between the two vessels and the diaphragm pump. In the illustrated embodiment on the lid of each air-vessel is provided a valve (cock, slide or the like) 8 and 9 respectively, in order to establish communication between the interior of the vessels and the atmosphere. The discharge opening of the valve or slide can be adjusted accordin to requirement by operating a rotatable linob or button 10 and 11 respectively. In order to continuously regulate the pressure below the atmospheric pressure in the suction air-vessel or the pressure above the atmospheric pressure in the pressure air-vessel, each vessel is connected to a mercury gauge 14 and 15 respectively by on rnono'rnte nmrom BREATHING on nnsrim'rron.

means ofpipes 12, 13, the position of the gauges being indlcated on suitable dials arranged on a single dial-board 16.

'--'P1pes-17 and 18 establish communicat'on between the two air-vessels 5 and 4 respectively and a three-way cook 19, which ac? cording to the position of its operating handle 20 and by means of the pipe 2l-cstablishes communication between the interior of the curved member 22,. resting closely upon the breast and belly of the patient and the pressure air-vessel or the suction air-vessel;

The essential feature of the apparatus according to the present invention consists in that by means of the two adjustable valves 8 and 9 the intensity of the effect of the employed pressure and'suction can be regulated se arately and according to requirement,

w ile. uninfluenced by this regulation the duration of the pressure or suction action on the patient can. be varied by the three-way cock within any desired limits and in the required succession. Thereby it is of, advantage to secure the three-way cock not on the curved member but, by means of suitable clamping screws 23, on the edge 24 of the couch or table on which the patient lies.

During the suction period the curved I member is firmly pressed against the body of the patient by means of the pressure of the outside air. However if the space underneath the arched or curved member 22 is filled with compressed air, difiiculties arose with respect to the tight fit of the edge of the arched member against the body. According to the present invention these difficulties have been removed by arranging an inwardly extending broad strip 25 right round the the edge of the member 22 (Fi 2). This strip preferably consists of so t rubber or of any other softmaterial, which readily adapts itself to the shape of the body of the patient. This inwardly extend ing strip 25 is pressed against the body of the patient by the pressure within the arched member 22.

In the modified construction of the arched member shown in Fig. 3, the bottom of the member 22 is closed by a rubber-diaphragm 27, which in its central partis provided with a number of perforations 26 and is closely Elli pressed against the body of the patient durdiaphragm and the body of the patient during the suction-period, which during the increasing pressure below the atmospheric pressure in the space underneath the arched member would cause the diaphragm to be blown up and choke the opening of the arched member from the inside, thus rendering impossible any further suction-action.

I claim- 1. An apparatus for effecting artificial respiration comprising a suction air-vessel, a pressure air-vessel, a hollow arched rigid member communicating with said air vessels and adapted to be placed on that portion of the body of the patient below the chest, the hollow rigid member being open on that portion thereof which is placed on the body,

a soft flexible member secured at its edge to the opening in said member and extending inwardly in the plane of the open end of the member, and having at least one opening therein, to revent'communication between the surroun ing atmosphere and the member when the latter is communicating with either the suction aiir-vessel or the pressure air-vessel, and means for permitting and regulating as desired the communication between either of the said vessels and the said rigid member.

2. An apparatus according to claim 1 wherein the soft flexible member has a plurality of openings therein.

In testimony whereof I afiix my signature. I
